Extended Outlook

Current radar loop for Houston, TX.

A complex of showers and thunderstorms will move across southeast Texas tonight and Wednesday morning. Rainfall amounts will average 1 to 3 inches with isolated totals around 5 inches possible. Localized flash flooding is the most likely impact if repeated strong storms move over the same area.

Rainfall amounts through Wednesday will average 1 to 3 inches with isolated totals up to 5 inches possible. Due to the primed soils, additional rainfall will result in runoff conditions resulting in street and river flooding potential.

A few storms tonight could become strong to severe with straight line wind gusts of 40 to 60 mph being the primary threat along with cloud-to-ground lightning and small hail.

Expect a trend toward warmer temperatures and decreasing rain chances later this week going into the weekend. Rain chances will increase late this weekend and early next week again as a weak front approaches the area.
